HELLO, the TODO list: CMS 1.1. I want only moderators to be able to add articles 1.2. Sorting of articles on frontpage: by date, by author, by last modification date, by ID - id can be set by moderator so they can choose which article will be shown as firs, which as second, and so on... 1.3. Articles rating - users can rate article from 1-5 1.4. When article is shown in full mode, I need a place (textbox or sth) where user can write that article is abusive, if they think so. Something like "report this article as inappropriate" and place for reason. Then the message with link to article have to be send to site admin. 1.5. Article Comments - users can add comments, moderators can delete them + there needs to be option, during article creation, that "this article cannot be commented" 2. BREADCRUMBS - I want it as links: Home -> Section -> Page somewhere in top of page PROFILES 3.1. While viewing a profile, I need a link to submit abusive profile. 3.2. I need subgroups. Standard user can be also in group: GROUP1 or GROUP2 - I need somehow to distinguish them. That's not all: standard user from group1 have some other profile fields: (login, e-mail, favorite music, favorit movie) than standard user from group2 (login, e-mail, favorite car, favorite drink). I want sort by those fields so maybe the easiest way is to create ONE BIG MODEL of USER whith all fields, and just leave them blank. 3.3. While viewing a profile, I need a link: ask to join chat (for 1 to 1 converstaion) 3.4. While viewing a profile, I need info if user is now talking on chat. 4. NEWSLETTER - I need easy to maintain way of sending newsletter to precisely chosen groups of users.
